JOHN P. THOMPSON, OF OLNEYVILLE, RHODE ISLAND.

LOOM-PICKER.

SPECIFICATION'fQrming part of Letters Patent N 0. 450,851, dated April21, 1891.

Application filed August 26, 1890. SerialNo. 363,128. (No model.)

To all whom it may concern:

Be it known that I, JOHN P. THOMPSON, a citizen of the United States,and a resident of Olneyville, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inLoom-Pick ers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a picker provided withthe support or clamp. Fig. 2 is a detail of the support or clamp, andFig. 3 is a view showing one of the old style of picker after a shortuse.

My invention relates to improvements in loom-pickers.

It has been found in practice that the continual striking of theshuttle-tip against the face of the picker-body soon Wears a hole insaid picker, also spreading it out wider than the space intended for itin the shuttle-box, causing it to chafe against the box andnecessitating the paring of the picker-body with a knife. This continuedchafing and paring soon wear out the picker-body and destroy it,necessitating its replacement; and the object of this invention is toprovide a spring-metal support or clamp, or its equivalent, which willbear against the sides ot' the picker-body and prevent its spreading,also presenting an elastic surface for the shuttle-tip to strikeagainst, breaking the shock of the contact and preventing theshuttle-tip from wearing a hole in the picker-body.

I am aware that it is not new to provide metal supports forpicker-bodies having an opening at the top to allow of the admission ofpieces of leather or its equivalent, and provide such supports with anopening in the surface to receive the point of the shuttle-tip; but ithas been found that to confine leather or its equivalent inside of asolid support or socket the continuous striking of the shuttle-tipagainst the picker-body will pack the leather or its equivalent so hardwithin the support as in a short time to destroy all the elasticity ofthe leather and render the picker useless. It has also been found thatto provide an opening in the center of the material comprising the bodyof the picker to receive the shuttle-tip is not satisfactory, for thereason that the said tip does not necessarily always strike at the samepoint on the pickenbody, and therefore, by placing this opening in afixed position, the tendency is to throw the shuttle out of its line andgive it a zigzag course across the loom. These above-n amed difficnltieswill be to a great extent, if not entirely, obviated by this invention.

To the accomplishment of this object the invention consists in theconstruction herein after disclosed.

In the accompanying drawings, A represents an ordinary leatherpicker-body provided with my spring clamp or support, said supportconsisting, preferably, of the springmetal plate B, although the saidclamp or support may be formed of other suitable material, such asrubber, &c. This plate Bis secured to the striking-face D of thepickerbody by means of the rivets or pins a a, se cured in therivet-holes]? b in the small lugs or ears 0 0, formed at each side ofthe plate, or it may be secured in any other well-known manner. Theplate B is provided with the arms O, which are turned over and clampedagainst the sides of the picker, as shown, thus preventing thepicker-body from spreading under the repeated blows of the shuttle-tip.The spring character of the metal plate 13 or its equivalent will breakthe force of the blows of the shuttle-tip and form an elastic surface toreceive said blows, thus preserving the elasticity of the materialcomposing the picker and preventing damage to both picker and shuttle.This spring metal support or its equivalent of other elastic materialmay be applied to all forms of pickers.

Having thus described the invention, what I claim as new therein, andthat which I desire to secure by Letters Patent, is-

1. The combination, with a loom pickerbody, of the herein-describedspring support or clamp, consisting of one continuous spring- 1oB,::provided with the lugs c 0, having the rivet-holes b b, and thearmsC, engaging the sides of the picker-body, substantially as and forthe purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN P. THOMPSON.
